its not showing any Robots /Drives avaliable

first check if netbackup in Media server is running fine nor not.?

if require restart the netbackup.

then see robtest is working fine , and able to communicate with the library without any errors or not

then show us the output of

scan

vmoprcmd -d

tpautoconf -t

tpconfig -d

from Media server. and from robot control host.

My tape library was substituted,

What steps were taken in NBU to remove old library and add new one?

Hi Marianne,

I removed the old library are the fields:

Storage units; tld(0)
Robots; tld(0)

Restarted node (Master) and (Midia Server)

In following add new robots.

In contact with support symantec I had to apply the following patch.
